I, the Dimensional Master, Start from the Backyard

The world is like a bitten apple, and the dimensional barriers are already riddled with holes. Fragments of magic and technology, phantoms of mythology and animation fall from the void, turning the world into a bizarre doomsday paradise. When everyone was struggling to survive in the ruins, Li Fan discovered that he could eat all these dimensional fragments. Devoured a "Magic Academy" fragment and obtained the Fireball and Elemental Servant Flame. After devouring the fragments of a "convenience store", I obtained a coffee machine with unlimited refills and a shop assistant who calls herself the goddess of good-for-nothing and refuses to leave. Devoured the fragments of a "Floating Fortress" and recruited a white-haired Tactical Doll. She is now in charge of the security system in the backyard, which is very efficient but consumes a lot of power. Devoured a fragment of the "Observer" and abducted a girl who claimed to be a humanoid terminal for contact with organic life forms. She's not very enthusiastic about anything, but she can help me predict where 99% of dimensional fragments will fall. What did you swallow today? It doesn't matter, they are all my backyard collection anyway. After all, if I want to survive in this collapsed world and transform it into something I like, I have to "eat" everything.
